Abstract The newly proposed method of vacuum preloading-flocculation-solidification combined treatment (physicochemical combined method) is being widely applied as a viable and efficient option for the treatment and resource utilization of high water content dredged mud. Complex coupling consolidation-solidification effect is involved in the early stage of this method, and exploring the early compression characteristics of modified mud is a prerequisite for revealing the coupling consolidation-solidification law. In this work, a series of laboratory tests such as one-dimensional consolidation and compression were carried out to investigate the effects of curing agent dosage, equivalent initial water content, and curing age on the early compression characteristics of high water content dredged mud treated by physicochemical combined method. The test results show that the degree of curing agent and curing age have significant effects on the compression characteristics and structural properties of high water content mud treated by the physicochemical combined method. The larger the degree of curing agent or curing age, the higher the yield stress and the stronger the structural properties of consolidation. In contrast, the equivalent initial water content has a lower degree of influence on the structural properties of high water content mud treated by the physicochemical combined method. The prediction equations for yield stress and destructing index are established by applying the concept of the compression model of structured soils. Finally, a simplified method for estimating the compression curve of high water content dredged mud treated by physicochemical combined method with different degrees of cementation is proposed based on test results. Laying a theoretical foundation for high water content dredged mud treated by physicochemical combined method as fill material for embankment engineering.
